Figure 4. OptEnet Converter Ethernet Connections
4. Each Ethernet media converter set top unit has an RJ45 connector located on the front.
Use this connector when making the copper Ethernet connection. If an RJ45 Patchcord is
provided proceed to
Patchcord. Pinout information is shown in
a. Use CAT 5E cable, strip back cable jacket to expose the four wire pairs, the metallic
sheath, and drain wire (if present).
b. Cut off metallic sheath and drain wire (if present) so that it is even with the outer
jacket of the cables.
c. The IEEE Specification for Ethernet 10 or 100BaseT(X) requires that two twisted
pairs be used and that one pair is connected to pins 1 and 2, and that the second pair is
connected to pins 3 and 6.
d. The IEEE Specification for Ethernet 1000BaseT requires that four twisted pairs are
used. One pair is connected to pins 1 and 2, pair two is connected to pins 3 and 6, pair
three is connected to pins 4 and 5, and pair four is connected to pins 7 and 8.
